CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims priority to United Kingdom Patent Application No. 2200569.8 filed on Jan. 18, 2022, wherein the entire contents of the foregoing application are hereby incorporated by reference herein.

BACKGROUND

The present invention relates to a modular system for implementing a darts environment.

Traditionally, a darts environment is created by mounting a dartboard and one or more ancillary components directly to a vertical wall in the desired configuration. Sometimes one or more free-standing components, such as free-standing lights, may also be positioned nearby. However, creating a darts environment in this manner is often time consuming and has little flexibility when changes are necessary.

A need therefore exists for a simpler and more dynamic system for implementing a darts environment.

DETAILED DESCRIPTION

Certain preferred embodiments of the present invention will now be described, by way of example only and with reference to the accompanying drawings

With reference to FIGS. 1 and 2 , a darts environment is illustrated. The darts environment is formed by a modular darts system 2.

The darts system 2 comprises a system hub 4, which supports a dartboard 6. The dartboard 6 is releasably and rotatably mounted to the system hub 4 using a board bracket 8.

A plurality of arms 10 are connected to the system hub 4. The arms 10 support ancillary components of the dartboard environment. As illustrated in FIG. 1 , the ancillary components may include dartboard surround elements 12, a dartboard lamp 13 and a dart holder 14. Other ancillary components, not shown, may include a scoreboard. The ancillary components are each secured to arms 10 of the system 2, as will be discussed in greater detail below.

The dartboard surround elements 12 each protect part of a wall or other surface behind the dartboard 6. The dartboard surround elements 12 are each an annular segment, and in the illustrated embodiment are quarter-segments. The dartboard surround elements 12 are formed of a foam material, such as polyurethane foam or the like.

The dartboard lamp 13 is a light source configured to illuminate part of the dartboard 6.

The dart holder 14 is configured to hold a plurality of darts, such as the six in the illustrated embodiment.

FIGS. 3 and 4 show the system hub 4 in greater detail.

The system hub 4 comprises a housing 16. The housing 16 is configured to be mountable to a wall or other vertical surface so as to support the weight of the system hub 4, the dartboard 6 and any ancillary components 12, 14. In the illustrated embodiment, this is achieved by means of a plurality of through-holes 18 sized to receive fasteners, such as screws 5, to secure the system hub 4 to the wall.

The system hub 4 further comprises a spirit level 20, which is formed on a front side of the system hub 4, so as to be visible when the system hub 4 is mounted to the wall. The spirit level 20 allows an installer to easily verify that the system hub 4 has been mounted at the correct orientation.

A rear surface of the system hub 4 is provided with a plurality of damping members 22, arranged to be positioned between the housing 16 and the wall, when the system hub 4 is mounted to the wall. The damping members 22 serve to reduce noise transmission when the dartboard 6 is used.

Optionally, a front surface of the system hub 4 may also be provided with a plurality of damping members 23 (not shown in FIG. 3 ), arranged to be positioned between the housing 16 and the dartboard 6. The damping members 23 similarly serve to reduce noise transmission when the dartboard 6 is used.

The system hub 4 comprises a bracket mount 24 configured to retain the board bracket 8. In the illustrated embodiment, the bracket mount 24 is in the form of a female bayonet socket. However, any suitable interconnection may be used, such as a screw thread connection or the like. Advantageously, a bayonet allows simple connection of the board bracket 8 to/from the system hub 4, without the use of tools, whilst still retaining the board bracket 8 securely in a desired orientation.

The system hub 4 also comprises a plurality of arm apertures 26, each configured to receive an arm 10. Each of the apertures 26 is sized to closely fit the respective arm 10. The system hub 4 is configured to releasably retain each arm 10 within the respective aperture 26. In the illustrated embodiment, this is achieved using a magnet 28 retained within each aperture 26, for example at an end of each aperture 26. However, other means of arm retention may be used, as appropriate, such as a friction fit or interlocking mechanical retainers.

FIG. 5 shows the internal construction of the system hub 4.

The housing 16 of the system hub 4 comprises a front housing shell 16 a and a rear housing shell 16 b, which are held together by fasteners 16 c, such as screws. The housing shells 16 a, 16 b form an enclosed interior region of the system hub 4.

The system hub 4 comprises an electrical inlet for receiving electrical power, such as mains electrical power. The electrical inlet comprises a cable 30 extending from the housing 16 and terminating in a plug for connection to a mains electrical outlet so as to supply electricity to the system hub 4. Alternatively, the electrical inlet may comprise an electrical inlet socket on the housing 16 for connection to such a cable 30.

Within the interior region of the system hub 4 is provided electrical circuitry (not shown). The electrical circuitry may receive the power from the electrical inlet. The electrical circuitry may comprise an electrical transformer and/or a rectifier. In other embodiments, a transformer and/or rectifier may be additionally or alternatively provided outside of the system hub 4, for example in a power supply adaptor of the cable 30.

The system hub 4 further comprises one or more electrical outlets (not shown) for supplying electrical power to an ancillary component 12, 13, 14. The electrical outlets receive power from the electrical circuitry inside the system hub 4. The electrical outlets may comprise sockets on the housing for connection to cables of the ancillary components 12, 13, 14, such as a cable 32 of the lamp 13. The electrical outlets may take any form, but in one embodiment take a standardised form, such as a USB socket.

Whilst the cables 30, 32 are shown exposed in the figures, in exemplary embodiments the cables 30, 32 may run within channels of the arms 10. This is aesthetically more appealing, and also protects the cables 30, 32 from accidental damage.

FIGS. 6 to 8 show the board bracket 8 in greater detail. The board bracket 8 is a mechanism for securing the dartboard 6 to the bracket mount 24 of the system hub 4.

The board bracket 8 comprises a dartboard mounting plate 34 for connection to the dartboard 6, and a mount connector 36 for connection to the bracket mount 24 of the system hub 4.

The board bracket 8 is configured so that when the dartboard mounting plate 34 and the mount connector 36 are pulled apart from one another, they are able to rotate relative to one another about an axis A that extends through the centre of the board bracket 8 and dartboard 6. However, when the dartboard mounting plate 34 and the mount connector 36 are held together, they are prevented from relative rotation, and are locked in one of ten (10) equiangular spaced positions. A biasing member in the form of a spring 38 is configured to bias the dartboard mounting plate 34 and the mount connector 36 against one another.

Thus, the board bracket 8 provides a first configuration in which rotation of the dartboard relative to the mount is prevented (as shown in the Figures), and a second configuration in which rotation of the dartboard relative to the mount is permitted (not shown).

Dartboards often wear unevenly, in particular around the “20 segment”. Therefore, it is common to periodically rotate dartboards to spread the wear more evenly. A standard dartboard has order-ten rotational symmetry (so long as the number ring is removable or rotatable), and therefore rotation in increments of 36° spreads the wear of the dartboard without impeding play.

In order to orient the dartboard 6 in one of the predetermined positions, the board bracket 8 comprises a plurality of apertures 40 formed in the mount connector 36, and a plurality of protrusions 42 formed on the dartboard mounting plate 34. The apertures 40 form positioning features and are equiangularly spaced to define the locked positions of the dartboard 6. The protrusions 42 form locking features and act to engage the apertures 40 to lock the dartboard 6 in the respective position.

In the illustrated embodiment, there are ten (10) apertures 40, and five protrusions 42. However, only one protrusion 42 is required for operation of the board mount 8.

Furthermore, the board mount 8 would still function if the apertures 40 were provided in the dartboard mounting plate 34 and the protrusions 42 were provided on the mount connector 36. However, the present arrangement advantageously aids in installing the dartboard mounting plate 34 on the dartboard 8.

The apertures 40 and protrusions 42 are each circular or cylindrical in the illustrated embodiment. However, other shapes may be used so long as they engage to retain the dartboard 6 in the respective position. Furthermore, the illustrated protrusions 42 have chamfered tips so as to guide them into the respective apertures 40 if the dartboard 6 is not exactly aligned in the respective position.

The board mount 8 comprises a plurality of fastener holes 44 for receiving fasteners (not shown), such as screws, to secure the board mount 8 to the dartboard. The fastener holes 44 are configured to align with the apertures 40 of the dartboard mounting plate 34. Thus, the fasteners can be installed in the respective fastener holes 44 through the apertures 40. In the illustrated embodiment, five fastener holes 44 are provided. However, more or fewer fasteners may be used.

As discussed above, a spring 38 is provided to bias the dartboard mounting plate 34 and the mount connector 36 towards one another. The spring 38 is a coil spring and is trapped between two flanges 46, 48; a first flange 44 being connected to the dartboard mounting plate 34, and a second flange 46 being connected to the mount connector 36. The first flange 44 is on a dartboard-distal-side of the spring 38, and the second flange 46 is on a dartboard-proximal-side of the spring 38, such that the spring 38 biases the dartboard mounting plate 34 and the mount connector 36 towards one another.

The dartboard mounting plate 34 comprises a shaft 48 about which the spring 38 is received. The shaft 48 is configured to hold a cap plate 50 by means of a fastener 52, such as a screw. The cap plate 50 forms the first flange 44 when connected to the shaft 48.

The mount connector 36 comprises a spring tube 54 that extends axially away from the dartboard 6 and receives the spring 54 within a bore of the spring tube 54. The second flange 46 is provided within the bore of the spring tube 54. An inner edge of the second flange 46 serves to position the shaft 48 of the dartboard mounting plate 34, and an inner edge of the spring tube 54 serves to position the cap 50 of the dartboard mounting plate 34. This arrangement constrains relative movement between the dartboard mounting plate 34 and the mount connector 36 to axial movement along the axis A, and rotational movement around the axis A.

A pair of bayonet pins 56 are provided on the outside of the spring tube 56 to provide the bayonet connection to the mount 24. The board bracket 8 also comprises a bayonet biasing member, such as a rubber washer 58 provided around the spring tube 54. The bayonet biasing member provides resistance against detachment of the bayonet pins 56 from the mount 24 of the system hub 4.

FIGS. 9 and 10 show details of the arms 10 of the system 2. The arms 10 are configured to be interchangeable, and all have the same cross-sectional shape, as shown in FIG. 10 .

The arms 10 are formed from a strong, stiff and light, material, such as aluminium or polycarbonate. The arms 10 in the illustrated embodiment are formed by extrusion.

The arms 10 each comprise a magnet 58 formed on at least one end. The magnet 58 is positioned so as to engage a magnet 28 of the system hub 4 when inserted into one of the apertures 26 of the system hub 4.

The arms 10 have a substantially rectangular outer cross-sectional shape. A height and a width of the outer shape of the arms are different lengths, so as to restrict the orientations that the arms 10 can be inserted into the apertures 26 of the system hub 4.

The arms 10 each define four channels 60, one on each side of the arm 10, extending lengthwise with respect to the arm 10. The channels 60 are each the same shape, and are configured to permit attachment of an ancillary component to the channel 60. The channels 60 thus form tracks that permit movement of the respective component along a lengthwise direction of arm.

Advantageously, the components may each comprise at least one connector configured to connect to the channels 60. Thus, the components each comprise a standardised connector, which simplifies interconnections within the systems 2.

In addition to attachment to the ancillary components of the system 2 that form the dartboard environment, the arms 10 may also permit attachment of other fasteners or mounting components. For example, the ends of the arms 10 may be configured to connect to fasteners that connect to a further arm 10, thus allowing extension of the arm.

Additionally, one or more of the arms 10 may be comprise fastener holes for connection to a vertical surface. Thus, instead of using fastener holes 18 to secure the system hub 4 to a wall, the system hub 4 may be supported by the arms 10, which may be connected to the wall.

In a further embodiment, one or more of the arms 10 may be configured to stand vertically, and to support the system hub 4. The vertically-standing arm(s) 10 may be configured to connect to a foot, optionally having casters, which may stand on the floor. Thus, in this embodiment, the system 2 may provide a free-standing standing darts environment.

FIG. 8 shows an alternative implementation of a modular soft tip darts system 102. This modular soft tip darts system 102 forms a soft tip darts environment, i.e. a darts environment for use with soft tip darts.

The modular soft tip darts system 102 shown in FIG. 11 shares many similarities with the modular darts system 2 described above, and therefore only the differences will be described. Like elements are labelled with the same reference sign, but incremented by 100.

In the modular soft tip darts system 102, the system hub 104 comprises an integral soft tip dartboard surface 106. A soft tip dartboard surface 106 typically comprises a plastic board with moulded holes that receive plastic-tipped darts. Due to the nature of soft tip darts, it is not necessary to periodically rotate a soft tip dartboard surface 106. Thus, the soft tip dartboard surface 106 can be integrated with the system hub 104 and a separate dartboard and board bracket are not required.

The system hub 104 may further comprise a digital scoreboard 115, and the system hub 104 may include integral scoring electronics for automatically calculating a score when a dart hits the soft tip dartboard 106.

Similar to the system hub 4 of the modular darts system 102 described above, the system hub 104 of the modular soft tip darts system 102 comprises a plurality of apertures (not visible) that receive arms 110 for supporting ancillary components such as a lamp 113.

Also, similar to the system hub 4 of the modular darts system 102 described above, the system hub 104 of the modular soft tip darts system 102 may be configured to connect directly to the wall via fasteners (not shown) or may be supported by the arms 110 in any of the configurations described above.
